<span class="explanation-format__ClueExplanation">'<span class="explanation-format__original">broke free</span>' is the definition.<br/ ><span class="explanation-format__explanation">(I've seen this before)</span><br/ ><br/ >This is all the clue.<br/ ></span>
(Other definitions for escaped that I've seen before include "Fled from captivity" , "Got away from captors" , "Evaded" , "Broke free, got away" , "Got away, broke loose" .)
